Swedish regulator says contraceptive app works as advertised

The Swedish Medical Products Agency has decided that Natural Cycles, the first app to be certified for contraceptive use, works like it says it does. It launched an investigation into the app after Stockholm's Södersjukhuset hospital reported that it caused 37 unwanted pregnancies. That number was taken from a study involving 668 women who went to the hospital seeking an abortion. Now, the Swedish MPA has closed its investigation after concluding that the rate of reported unplanned pregnancies among Natural Cycles users is in line with the typical use effectiveness rate of 93 percent, based on a study of over 22,000 women that the company conducted in 2017.
